Emerse and Submerse

[sweetlips200278]

Is there a way to define the above? It seems quite confusing. 1 type of plant can be both? example tenullas, nana, Hemianthus callitrichoides (HC)...etc. So how does one tell when they are emerse and when they are submerse?

Worse part come in when the plant can even convert from emerse to submerse vice versa!

No one? Let me try:-

Some plants can be both Emersed (E) and Submersed (S). E means Rising above the surface of water. S means beneath the surface of the water. For example, almost all Echinodorus genus can grow in both settings. Aquatic farms tend to grow plants emersed if they can. Reason, they grow at alarmingly fast rate in deep, nutrient-rich substrate. AND and... no algae problem. Downoi is also a good emersed example where farmers can grow them very fast in very wet and nutrient-rich substrate. Most Cryptocoryne are growth emersed when they are in farm. In wild, it is because of flood - they are submerged.

To answer your question - you cannot tell whether they are growth submersed or emersed unless you are a experienced person in plants. However, you can find out when you plant them in your tank. It usually take a few months for a certain Cryptocoryne to transform from emersed to submersed..By that time- algae already invaded your house

Given a choice - the plants will like to grow from submersed to emersed. Reason being plants are also fighting for survival and they want to reproduce faster. This is nature.

Btw, Blyxaa is a good example of emersed plants. They wither instantly when come in contact with air and wind.

Quite interesting to know this.

Would you recommend one to go through this process of conversion or just pick up the submersed one if the objective is to have a submerse plant in one's tank? Any different?

Ya. I recommend picking up the submersed plant if the intention is keeping/displaying them in a tank. But the emersed plants are so cheap if you get them from Teo Aquatic Farm.


Correction: Blyxaa is a good example of submersed plants

Seem like it is going to be a challenge for one who cant identify whether the plant pick up at the LFS is a Emersed or Submersed!

Thanks for all the advices.

The first thing is always to learn about the plant first before buying them. It makes our life easier. Most Echinodorus is easy. I think only Cryptocoryne takes a long time.. sigh
